Instruments for Industry, GT7525 Series TWT Amplifiers provide outstanding RF performance. These 2.5 to 7.5 GHz TWTA's (traveling wave tube amplifiers) have field-proven reliability and industry-leading performance. Making these amplifiers ideal for multiple high-frequency high power applications including but not limited to RF immunity testing. Operation safety and ease of use are paramount in IFI TWT amplifier product designs. The IFI GT7525 series includes a full complement of RF and hardware protection systems including high VSWR, over-current and voltage protection as well as redundant thermal and airflow sensors to prevent the TWT from overheating. In addition, the GT7525 series includes a state-of-the-art touch screen interface that is sophisticated, comprehensive, but yet simple to use. Our amplifiers feature modular construction and this concept of modular design minimizes internally produced EMI signal leakage and provides easy access for field service and rapid turnaround at depot level repair facilities. The touch screen interface shows forward/reverse power indication, system status, and self-diagnostic information. All the TWTA operating parameters are simultaneously available via the touch screen interface as well as over the remote bus. For remote operation GPIB, RS232, USB & Ethernet remote interfaces are included as standard. To meet individual application needs, the GT7525 Series TWT power amplifiers can be easily customized with harmonic filters or other options. With this capability and its reliable elegant design, the GT7525 series amplifiers are the perfect amplifier for your microwave needs. IFI offers different size packages and configurations to best suit your application.
